방법: MenuAction 만들기

  • 아티클

업데이트: 2007년 11월

다음 코드 예제에서는 디자인 타임 상황별 메뉴에 사용할 메뉴 작업을 만드는 방법을 보여 줍니다. Visual Studio에서는 이 작업을 폭넓게 지원합니다. 자세한 내용은 연습: MenuAction 만들기를 참조하십시오.

예제

다음 코드 예제에서는 WPF(Windows Presentation Foundation) 사용자 지정 컨트롤에 대한 디자인 타임 메뉴 공급자를 만드는 방법을 보여 줍니다. 이 바로 가기 메뉴 항목을 사용하여 사용자 지정 단추 컨트롤의 Background 속성 값을 설정할 수 있습니다.
